DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a curable resin molded article that provides a cured product with excellent flexibility, heat resistance, chemical resistance, toughness, and adhesiveness.

[Prior art and its problems]

Conventionally, thermosetting resin compositions that provide flexible cured products include those in which an inorganic filler is blended with a saponified ethylene-vinyl ester copolymer (Japanese Unexamined Patent Publication No. 143980/1983) and ethylene-vinyl acetate copolymer. A compound containing a cyanate ester compound having a cyanate group (Japanese Patent Application Laid-open No. 79245/1983) is known.

However, although thermosets obtained from these compositions have flexibility and toughness, they are unsatisfactory in heat resistance. On the other hand, epoxy resins and phenolic resins are known as resins that provide heat-resistant cured products, but the cured products obtained from these resins are not flexible and are prone to cracks and cracks. It has the following drawbacks.

Furthermore, a curable resin composition comprising a polyfunctional cyanate compound and a polyfunctional maleimide compound is also known (Japanese Patent Application Laid-open No. 129700/1983). The cured product obtained from this composition has excellent heat resistance, chemical resistance, etc., but does not exhibit flexibility.

According to JP-A No. 60-192779, a thermosetting resin composition consisting of a polyfunctional cyanate compound and a polyfunctional maleimide compound is blended with a low-crystalline or non-crystalline thermoplastic saturated polyester resin. Adhesive compositions have been proposed. The cured product of this adhesive composition exhibits flexibility based on the polyester resin. However, this composition was developed as a varnish and is not satisfactory for use as a thermoforming material.
